Because he's been injured...McKernan is significantly better as a KF and 2nd ruck compared to Bellchambers. If Leuenberger was injured or out of form then Bellchambers would be the next pick as first ruck but as a KF and 2nd ruck Bellchambers has been fairly useless as he is slow and uncompetitive.
